/* Answers — AiOS answer and card presentation spec (approved 23 Sep 2026; applied 24 Sep 2026).
   Tenant-agnostic: every colour derives from --accent / --ink / --line, every size from the --t-* ladder. Fonts and brand colours stay
   with the tenant configuration. Selectors are the production DOM (kit-renderer.js, v2-renderer.js, app.js), verified against develop
   f63c3afd; where the spec's reference CSS named a different class, the declarations were kept and the selector adapted:
     .p-document → .docrow (row), .p-button → .open (pill), .aios-answer-marker .persona → not restyled (owner kept production marker).
   Owner decisions 24 Sep 2026: card grid = spec auto-fill 280px; detail width = 2 × card + 50px; desktop answers keep the --ui-z scale
   above 1440 (D2), so a 4K answer is the 1440 answer, larger, with the same column count. */
